ABSTRACTWheels are one of the most critical components in automotive engineering. Their function is of vital importance to human safety. Wheels are components working under cyclic loading and different load spectrum considering the load amplitude and frequency [1][3]. Disc wheels intended for normal use on passenger cars have to pass three tests before going into production: the dynamic cornering fatigue test, the dynamic radial fatigue test, and the impact test [5]. Fatigue prediction has been an important issue in the design of aluminum disc wheels [2][3] . Wheels are clearly safety related components and hence fatigue performance and the state of stress in the rim under various loading conditions are prime concerns. Further, wheels continue to receive a considerable amount of attention as part of industry efforts to reduce weight through material substitution and down gauging.[5]

ABSTRACTThe steering system and steering column are the one of the most important devices of an automobile.it is a very crucial part to attain stability and steady movement of the vehicle. A universal joint consist of two yokes, one on each shaft, connected by cross-shaped intermediate member i.e. spider. Yoke assembly are always subjected to torsion and shear. Motion transmission system of vehicles consist several components which sometimes encounter unfortunate failures. Yoke assembly are rotating part and sometimes suffer from fatigue by application of variable torque.in this paper finite element analysis of the component is carried out to find the stress and displacement of the final product. For modelling of the component ProE software is used. Pre-processing work like meshing and analysis work is carried out in HYPERWORKS software. Using FEA analysis, we can identify the nature and characteristics of stresses acting on the yoke and evaluate the influence of the load/mass geometry/boundary conditions over the yoke.

ABSTRACTThe heat exchanger for ‘dairy’ calls for an ingenious design for turning around the high volume of milk in short span of time. This work shall focus on determining the design alternatives for the heat exchanger. The current needs are met with a shell and tube type heat exchanger with support offered for volume of about five thousand liters of milk per day. Mathematical modelling coupled with computational methodology shall be explored for ramping up the volume in excess of twenty thousand liters. ANSYS Fluent shall be deployed for finding solution while mathematical model shall offer alternative methodology for validating the solution.
